SAFETY-PLATFORM MECI-IANISM.

Appncarion ined :rune 1s, 1921. serial 1ro. 478,776.

To a-ZZ whom t may concern Be it known that we, FRANK Hannity and JAMES S. DoYLn, both citizens of the United States, and residents, respectively, of Yonkers and Mount Vernon, in the county of l'Vestchester, State of New York, have made a certain new and useful invention in Safety- Platform Mechanism, of which the following is a specification.

This invention relates to safety platform mechanism, anduparticularly to gap filling devices between `the sides of trains or cars and the approximate edge of a station or landing platform-` j The object of the invention is to provide means which are simple and efficient for filling the gap between the sides of trains or cars and the adjacent edge of a station or landing platform` as a safety means to prevent accident or injury to passengers while boarding or alighting from the car or train, and particularly to a gap filling structure for use where the track rails on which the cars or trains operate are curved at the station where the gap filling device is to be employed.

A. further object is to provide the station platform or landing withmovable sections or segmentswhich are advancedagainst the side of the car or train when the latter is standing opposite the edge of the station platform. in order to lill the space or gap between the car or train and the stationary part ot' the station platform or landing, and wherein one or more of the movable platform sections or segments are laterally movable so as to automatically adjust itself to the angle of inclination'ofv the car sides to the edge of the platform where the track is `curved at the station or platform.

A further specific object of the invention to provide a station platform or landing with sections or segments which are advanced towards or retracted from the side of the :ar or train when standing at a station, and one or more of which sections are automatically movable laterally to accommodate themselves to the angle of inclination of the side of the car or train with relation to the platform edge wherein the edge of the The invention consists substantially in the construction, combination, location, and relative arrangement of parts, all as will be more fully hereinafter set. forth, as shown by the accompanying drawings, and finally pointed out in the appended claims.

In Patent No. 1 149 759 O'ranted to us on 7 7 7 23 August 10, 1915, for safety platform mecha-4 nism, we have pointed ont that in the construction of street and railway track systems such as subway, elevated and surface lines, and particularly where boarding and alighting platforms are pro-vided for passengers to step directly to and from the same in alighting from or boarding the ear or train standing alongside of the platform, it is frequently necessary to leave considerable space between the line Vof the side of the car or' train and the approximate edge of the station 0r platform in order to provide the necessary clearance therebetween, and that particularly is this true where the station is located on a. 'curve of the track rails. Such a space between the car or train and the station platform is a fruitful source of accident and injury to passengers who are required to alight from or to board. the car by stepping across such space and who frequently miss the ear or the platform and fall down or are crowded from the car or the platform into suoli space, thereby recei ving injury. 1n said patent we have shown, described and claimed broadly an arrangement of safety platform mechanism where.- in a stationary and a movable platform portion are arranged to operate in the same horizontal plane with means for moving the movable sections of the platform towards and from the side of the car or train located opposite the platform. We have .found that in the case where stations are located on a curve of the track rails, and more particularly where the cnrve of the track rails at the station necessitates a convex curvature of the edge of the platform, that when the movable sections of the safety platform mechanism are advanceil towards the side of a car or train standing on the track rails alongside the platform edge, there is still a considerable space left between the forward edge of the advanced platform section and the side of the car adjacent thereto by reason of the inclination of the side of the car or its tangential relation with reference to the edge of the platform section. The result is that when the movable section of the platform is advanced against the side of the car or train the angular or tangential relation between the front edge of the movable platform section and the side of the car is not affected, and that when the movable section of the platform has been so advanced there still remains a dangerous gap or space between its advanced edge and the side of the car. It is amongr the special purposes of our present invention to avoid this defect and to provid(l means whereby one or more of the movable platform sections may automatically adjust itself when advanced against the side of the car or train standing opposite thereto so that the front edge of the platform section or sections will lie parallel to and against the side of the ear notwithstamling the angle of inclination or tangential relation of the side of the car to the platform edge.

In carrying ont our present invention therefore we propose to employ means whereby one or more of the movable platform sections may be automatically tilted laterally when advanced so as to accommodate itself or the front edge thereof to the angle thereto of the side of the car or train.

Generally speaking, a structure embodying our present invention includes the following elements, namely,-first. a foundation frame or framework upon which are mounted movable frames which carry the Aable sections, which framifes are mounted `no part of our present invention.

and guided upon` the foundation frame.

work; and, third, the framework of the statlonary portion of the platform between which and the foundation framing the frames of the movable sections are posi-` tioned, held and guided, and in accordance with our invention we so mount one `or `more of the movable sections of the platform as to permit the same to tilt laterally upon its guiding supports so as to enable the front edge or edges thereof to automati ally adjust themselves to' the angle of inclination of the side of the caror trai-n into Contact with which said sections are advanced. le employ power mechanism to effect the advancing; and retractinir move ments of the movable sections of the platA form, but the structures of such power mechanism and the control thereof are fully disclosed in our prior Patent No. 1,149,759 above referred. to, and therefore those features and the specific details thereof form liefen ring particularly to FigjQ the foundation frameworlr'is indicated generally at 30, the movable platform section framework is in dica'ted generally at 3l, and the framework 'for the stationary portion of the platform indicated generally at 82, it being,` observed that the framework 3l `of the movable platform section is positioned between the foundation framing' 30 and the stationary platform framing 32 and is held and ,euided in tliis relation. By reference to Fig. l we have shown a safety platform arrangement as a practical `embodiment of our `invention wherein three sections of inovable platform portions are shown as adjacent the front edges of said platform `wise be anpgularlyadjustable.

sections, and we have indicated the section 2&4: as being mounted for angular movement in order that its front edge may autonmtn ically adjust itself to the angle of inclination. of the adjacent side of the car to the edge of the platftn'in.` Our invention, how ever, is not to be limited. or restricted in `this respect as it is obvious that any number or all of the platform sections may liltelt will be understood of course thaton the front edge of the stationary part of the platform indicated at 3T a series of spaced apart fingers 38 are mounted, `and that projecting' rearwardly from the front ed gre of the movable sections of the platform cooperatin,o1 fingers 39 are employed which alternate with the fingers 38, the upper surfaces of these fingers constituting,` the stand- `Figs. 2, 20, 2l. and 22.

ing area of the platform surface, all as more fully described in our former patent referred to above.

The foundation framing 30 is illustrated more in detail in Figs. 9, lO, 1l and 23, and includes in the particular' embodiment of our invention which wedhave selected for illustration vertical standards 40, upon which' is supported a frame member all which carries traclr rails 4Q, along; which operate the supporting; .rollers 43 of the movable platform sections.` Also mounted on the foundation frame` are the guide rollers lf/i., ll, see Figs. 6, 7 and 8, which cooperate with the frame of the movable platform section as presently will be more fully explained. The :'oundation frame also carries one or more broad. track members 4:7, upon which the sujiiporting rollers 43 at the approximate edges of the movable platform sections may be carried as seen most clearly in Fig. 19. il tie member 48, see Figs. 9 and l0, is mounted at the front upper edge of the foundation frame. Suitably supported upon Athe foundation framingf are the motors, by means of which Jlthe movable sections of the platform are operated. ln Fig. 3 we have shown two motors 49, 50, both connected to an operating lever 5l for a movable section of the platform. ln Fig'. et we have shown a single motor 52 connected by means of a lever 53 to the movable platform sections. Our present invention however is not to be limited or restricted in respect to the number of motors employed nor to the manner of connecting them to the platform sections, nor with respect to the manner of control of said motors, these being features disclosed and claimed in our prior patenti-above referred to, and forminn; in the details thereof no part of our present invention.

The Iframework of the stationary portion ofthe platform is shown more in detail in The particular structure of this framework is of no material consequence, any suitable or conven supported by suitable columns or the station 'foundation indicated. at 57 in Fig. 2. rllhe frames for the movable sections of the platform are disposed between the stationary frame for the stationary portion of the platform and the foundation frame` i worl;` as indicated in Fig. 2, andas above explained` The movable frame `is shown more fully in detail in Figs. l2 to 17 inclusive, and consists of end portions 59, 60,

6l, connected by braces 62, and having connected thereto suitable yoke devices 63 for connection to the motor by which the frame is advanced or retracted. larried by each movable frame are longitudinal stringers or members 66 forming a track, or way in which are received the guide rollers 45 of the foundation frame. 'ihese guide rollers are positioned horizontally and serve to guide the movable frames in their advancing and retracting movements. lf desired, the guide rails 66 may be faced with Wearing plates indicated at 67. In Fig. 7 we have indicated the tracks 66 as extending 'transversely all the way across the .movable frame, while in Figs. S and l2 we have shown the arrangement for accommodating the lateral movement of the movable frame. XV here the movable platform section is employed which not automatically adjust-able laterally the guides 66 for the guide rollers 45 extend transversely across the movable frames, but where the section is designed to be. permitted to tilt horizontally in accordance with ourinvention and to effect the automatic accommodationof its front edge to the line of inclination of the car body side, the guide channel members 66 are Hai-ed away from each other at their rear ends as indicated at 68, see Fig'. l2, the wear plates 69 therefor being correspondingly flared. Vith this arrangement a sufficient space. is permitted at the flared portions 66 rof thel guide channel side members to permit a lateral sidewise rocking or tilting movement of the frame after the frame has been advanced to a point where the guide rollers l5 occupy the space between the flared portions 68. The front frame members 60 of the movable platform sections have mounted therein buffer rollers the function of which is to take the impact of the forward edge of the movable fermes when said frames are advanced against the sides of the cars. Therollers operating` on the.` track rails 42 support the movable frames, said rollers beingl journaled in suitable boxes indicated at 'Tl mounted on the movable platform section of the frame. it will'be observed that two guide rollers lflf-t, 45,( are employed for each movable frame7 said guide rollers being positioned in line with each other transversely across the movable frame. This affords an efficient bearing for the frame inasmuch as it is guided at different points in its transverse width. Only the rearmost guide roller 45 is disengaged from the side walls of the guiding channel therefor in the case of the automatically kadjustable platform sections when said sections are advanced sufficient-ly `for the roller 45 to enter the space formed by the enlarged or flared portions 68 of the guide, and in the laterally adjusting movements of these sections said sections fulcrum around the forward guide rollers t4- thereof. lnasmuch as the automatic laterally adjusting movements of the platform sections :rre accomplished only after the sections have been advanced to abut against the side of the cars standing opposite thereto the tendency is for the rearmost supporting` rollers ft?) ot the movable sections to be raised slightly above. or the pressure thereof slightly ein larged from the track rails 42, il-T. upon which they operate, and consequently no diiliculty is experienced in said rollers sliding laterally over the upper surface of their supporting track rails during the luterallv adjusting movements of said` frame sections. The extent of such lateral movement is comparativcly slight, and we have experienced no di'liiculty with respect to said supporting rollers sliding laterally over the surfaces of their supporting rails in the practical operation of the apparatus.

The buffer rollers 70 are mounted in frames 72 carried by the front rail 6d ot' the movable frame. The front edge member 6'.) of the movable frame has secured thereto angle member 71tto which are secured the fingers 39, see particularly Fi The rearniost ends of said fingers are secured to a frame member T6 of the movable frame.

As above explained the lingers 38 of the stationary portion of the platform are supported at their rear ends upon a freine inember of the stationary frame. The front ends of said fingers 38 are secured to n. niember T7 which is carried by a bracket TS supported upon the front member 416 of the foundation frame.

In Fig. 6 we have shown a bracket TS) carried by one of the vertically extending stainlards 40 of the foundation frame7 and which bracket serves to support -the stationary frame 32.

(ilrdinarily the bulier rollers To are mounted at the forward corners ox Adie movable sections olI the platform. inasmuch :is these buffers are required to talse coin-'Ederable stress and strain in the performance ol' their buffer function we pre for to elliciently brace the frames 72 in which said rollers are mounted. No accomplish this by providingl angle braces S() which are sflecnred to the frames 70 and to the framework ol" the movable platform section.

From the foregoing description it will be seen that we provide a simple and ellieient arrangement whereby the landing platform is equipped with extensible or relatively movable portions which are mounted to be projected from the edge of the landing platform and which move and have their surfaces in the same plane with that of the platform one or more of said movable sections not only being movable toward and Alltl away from the edge of the platform but also being mounted for swiveling or horizontal tilting movement so'that its` outer edge will automatically assume a position parallel with and against the s'tde of a car standing opposite it even though the side of the car stands at an angle of inclination relative to the edge of the. landin thereby practically filling up the gap or space between the platformand the side of the car, notwithstanding the angular relation of the side of the car to the edge of the platform, such as would be produced where the track along which the car operates is curved at the landing platform and hence affording safety to `passengers passing between the car platform. It will also be seen `that guides are provided for: guiding the movement of the movable sections of the platform, the gnidingconnections being so arranged in the case of theautomatically adjustable platform section as to permit the horizontal swiveling or tilting adjustment of said section to be effected by fulcruming about one of the guides of said section.

It will be understood that many changes in the details of structure and arrangement will readily occur to persons skilled in the art and still fall within the spirit and scope of our invention. While therefore we have shown and described a specific structure our invention as defined in the claims is not to be limited or restricted to the exact details as shown and described, but having now set forth the objects and nature of our invention and a structure embodying the principles thereof what we claim as new and useful and of our own invention and desire to secure by Letters Patent is,-
